+## Phase 11 — Public Site Enhancements
+
+### 11.A — `/cuts/{id}` album-detail page
+
+**Landed:** 2026-06-16 on dev.
+
+- **What:** New public Cut album detail page at `/cuts/{id}`. Composes `ReleaseDetailScaffold` via a generalized `Header` slot (left meta: name, artist, genre, year, Play + Share) and a `BodyContent` slot (right theme-bordered cover image; `TrackNumber`-ordered track list with per-row play). `CutDetailBase` carries the multi-track prerender bridge across the prerender→WASM seam (following the `ReleaseDetailBase` pattern); `CutDetailViewModel` holds the loaded state. Header Play and per-row play wire into the existing single-slot `IPlayerService` (`SelectTrackStreaming` / toggle). A `PlayAlbum` method contains a documented one-line seam for a future swap to `IQueueService.PlayRelease` — queue integration is a deferred follow-up, not live in this wave. Reuses the existing `GetById` release endpoint and the `releaseId`-filtered track page; no new API surface. Track ordinal (`TrackNumber`) was verified already built and consumed correctly — no new schema.
+- **Why:** Cuts (Studio releases) had no single-release detail page — `/cuts` cards navigated to `/tracks?album={title}` (a track-cardinal view). This makes the album the primary navigable unit on the public site for Cut releases, completing the per-medium detail page set alongside `/sessions/{id}` and `/mixes/{id}`.
+- **Shape:** New `CutDetail.razor` + `CutDetailBase.cs` + `CutDetailViewModel.cs` in `DeepDrftPublic.Client`. Composes `ReleaseDetailScaffold` with `Header` and `BodyContent` render fragments. Track list ordered by `TrackNumber`; per-row play binds to `IPlayerService` (`SelectTrackStreaming` / toggle). `PersistentComponentState` bridge is owned by `CutDetailBase` (keyed `"cut-tracks"`).

+
+### 11.F — play-queue `IQueueService`
+
+**Landed:** 2026-06-16 on dev.
+
+- **What:** A separate `IQueueService` orchestrating album (ordered multi-track) playback above the single-slot player. Holds an ordered track list, a current index, and `Next()`/`Previous()` skip navigation wired into the player-bar controls (skip-forward gated on `HasNext`, skip-back gated on `HasPrevious`). Auto-advance via a new `IPlayerService.TrackEnded` event (raised only on organic end-of-stream): `OnTrackEnded` advances the queue only when `player.CurrentTrack.Id == queue.Current.Id` — an `Id`-equality cross-advance guard that prevents a superseding direct-play call from accidentally advancing the queue. `Attach(IStreamingPlayerService)` binds the queue to the player (called once by `AudioPlayerProvider`); loading a track list into the queue is a separate concern via `PlayRelease`. No detach-on-direct-Play mechanism. Provider-owned and cascaded — not DI-registered, by design. Surface members: `Items`, `CurrentIndex`, `Current`, `HasNext`, `HasPrevious`, `QueueChanged` event; methods `Attach(IStreamingPlayerService)`, `PlayRelease(IEnumerable<TrackDto> tracks, int startIndex = 0)`, `Next()`, `Previous()`, `Enqueue`, `EnqueueRange`, `Clear`.
+- **Why:** The player was single-slot only. The Cut album detail page (11.A) needs "play album" — an ordered queue that advances through tracks end-to-end. Absorbs the queue half of Phase 1 §1.3 (the preload half remains deferred). Prerequisite for a future `PlayAlbum` integration in 11.A; also exposes skip controls in the player bar.
+- **Shape:** New `IQueueService` interface + `QueueService` implementation in `DeepDrftPublic.Client`. `IPlayerService` gains `TrackEnded` event. Player bar gains skip-forward and skip-back controls bound to `IQueueService.Next()`/`Previous()`, gated on `HasNext`/`HasPrevious`. `Attach(IStreamingPlayerService)` wires the queue to the player without constructor growth; `PlayRelease(IEnumerable<TrackDto>, int)` loads an ordered track list and starts playback.
+

+
+### 11.G — release Description schema slice
+
+**Landed:** 2026-06-16 on dev.
+
+- **What:** New nullable `ReleaseEntity.Description` column (plain text, max 4000 characters) on the base release table, mirrored in `ReleaseDto.Description`. `TrackConverter` round-trip updated. Write-path plumbing threaded wherever `Genre` is: `UpdateTrackMetadataRequest` + upload form fields + `UnifiedTrackService` + `TrackManager` update path. CMS `AlbumHeaderFields` gains a multiline `MudTextField` for Description input. Detail-page rendering deliberately deferred — Description degrades cleanly (null renders nothing) so schema and render can land in either order. EF migration `20260616035252_AddReleaseDescription` authored; **not yet applied** (Daniel-gated).
+- **Why:** Commitment 8 from the Phase 11 spec. No `Description` member existed on `ReleaseEntity` or `ReleaseDto` prior to this wave. A base-release free-text field (uniform across all media) lets admins describe a release context, inspiration, or credits. Lives on the base release, not a per-medium satellite (consistent with Phase 9's open/closed spine).
+- **Shape:** `ReleaseEntity.Description` nullable string in `DeepDrftData`. EF `ReleaseConfiguration` adds max-length annotation (4000). `ReleaseDto.Description` nullable string. `TrackConverter` updated to map the field on both read and write paths. `UpdateTrackMetadataRequest` gains `Description` field. Upload form (multipart) gains `description` form field. `AlbumHeaderFields.razor` gains a multiline `MudTextField`. Migration `20260616035252_AddReleaseDescription` authored but not applied.
